I agree to the point that he should know and it’s okay to let it all out. He should know his wrong doing. But his response to the text should not bother you. I know and I understand sometimes we want this kind of closure and talk for maybe just one more time but girl let me tell you , you are so much more than him confusing you or giving you false hopes. Just let it out and don’t get affected if he Acknowledge it or not. It’s better if he does but even if he don’t just remember your worth and how you deserve someone better than him. :)
